Well those boxes could contain hundreds, maybe thousands of pounds worth of antique and modern jewellery.

131 year old UK auction house Fellows & Sons sources many of its most exciting items from people walking into its reception in Birmingham.

The firm has a number of unusual items up for sale at its next antique and modern jewellery sale on Thursday 18th October.

They include five Russian egg pendants. The hinged pendants are being sold individually and could fetch up to £100 each.

They can be viewed at the firm's website and in its online catalogue at
